3 AN OVERHEAD WATER TANK IS BUILT ON A HORIZONTAL GROUND. THE CURIOUS ENGINEER WANTS TO FIND THE HEIGHT OF THE WATER TANK SO HE WALKS DUE WEST OF THE OVERHEAD WATER TANK AND MEASURES THE ANGLE OF ELEVATION TO BE 28.4 DEGREES. HE THEN WALKS ON THE SOUTH DIRECTION OF THE WATER TANK AND MEASURES THE ANGLE OF ELEVATION TO BE 23.6 DEGREES. THE DISTANCE BETWEEN TWO POINTS IS 72.8m. QUESTION: WHAT IS THE HEIGHT OF THE OVERHEAD WATER TANK?
